$($Q$27-30)$ You own a $300,000$ sf office building that is fully occupied except for one $25,000$ sf suite. You recently signed a $5$ year lease for this suite. The lease is for $$150$ PSF but you have to provide the tenant with $$200$ PSF of tenant improvements and $6$ months free rent. You also owe the leasing broker a $4\mathrm{.}0\%$ commission. With the new lease in place, you expect the property to produce $$21$ million of NOI next year after accounting for the free rent. Someone has offered to buy the property from you for a $6\mathrm{.}0\%$ cap rate and the potential buyer believes that the sale price should be $$350$ million.

What NOI amount should the buyer be using to calculate the sale price?
